Understanding Wi-Fi Variants
summary
Clear mapping of 802.11 variants to frequencies, real throughput and range: legacy 802.11b 11 Mbps and 2 Mbps origins, 802.11g/a 54 Mbps, 802.11n up to 600 Mbps with MIMO, 802.11ac wave2 ~1.3–3.4 Gbps, 802.11ad/ay 60 GHz (short range <10 m, ~7 Gbps), 802.11ax Wi‑Fi 6 (OFDMA, MU‑MIMO, ~4× AC throughput), 802.11ah HaLow (900 MHz, kilometers, low power); Wi‑Fi Alliance certs cover interoperability, mesh is mostly proprietary despite an easy mesh standard, and WPA3 cracked means security is still unresolved; many APs need ~1.8 GHz quad‑core silicon.
